+## Licensing FAQ
+
+### Is internal SaaS infrastructure considered internal use?
+No. If the infrastructure supports a revenue-generating service,
+it is considered commercial use.
+
+### What if customers never see the node?
+Visibility is irrelevant. Revenue enablement constitutes commercial use.
+
+### What if we are a startup?
+Startups are commercial entities and require a commercial license.
+
+### What if we only use one workflow?
+Scope does not change license requirements.
+
+### Do proof-of-concepts require a license?
+Internal, non-customer-facing POCs are permitted.
+Production SaaS deployments require a license.
